How to Create a Curved, Extruded Logo

Final product image
What You'll Be Creating

In this tutorial, we will be creating a curved extruded logo which is based on the Videohive project Curved Chrome Logo. We will be going through a technique to create the curve effect with the help of masks. Additionally, we will use few expressions and some minor tricks to control the overshooting effect, extrude, and shadow with the help of only a few keyframes.

1. Creating the Base of the Project

Step 1

Create a new composition. The comp should be 1920x400.

Step 2

Insert your logo.

Step 3

Make another composition with the same Height and Width. Name it Logo + Stroke.

Step 4

Now insert your Logo comp in this composition and make a copy of it.

Step 5

Apply Fill and Simple Choker effect on the bottom Logo layer and use the following settings.

Step 6

Now right click on the bottom Logo layer, go to Layer Styles and add Gradient Overlay.

Step 7

Use the following Settings for Gradient Overlay.

Click on Edit Gradient option to apply different levels of color on it.

Step 8

If you solo the bottom layer, you will see something like this.

Enable both the layers to see the edges of the logo which I created in step 5 with Simple Choker effect.

2. Creating a Curved Extrude in the main composition

Step 1

Create a Full HD composition.

Step 2

Insert Logo+Stroke comp in this composition.

Rename it to Logo1.

Step 3

Create a new Adjustment Layer and rename it to Controller. Layer > New > Adjustment Layer.

Step 4

Apply two Expression Controls on this Adjustment Layer. Slider Control and Color Control.

Step 5

Rename these two Expression Controls to Curve Depth and Extrude Color.

Step 6

Now select the Logo1 layer and double click on the Rectangular Mask option to create a mask on it.

Then click on Shape to bring Shape Options. Now the initial values of Left and Right were and 1920 Respectively. I changed them to -1000 and 2920 to extend the mask on X axis only.

You can see now that the mask is bigger than the layer on the X axis.

Step 7

Duplicate the Logo1 layer and bring on the Position settings by pressing P while the layer is selected.

Step 8

Alt+Click on the stop watch to insert an Expression which will help us to create a Curved Extrude effect.

Step 9

Now insert this Expression in the Expression panel.

offset=thisComp.layer("Controller").effect("Curve Depth")("Slider")*-1;

The above script is connected to the Expression Control Curve Depth which will offset the layer from Logo1 by 1 pixel.

Step 10

Create 100 copies of Logo1 layer by duplicating it.

Step 11

Create a new Camera.

Step 12

If you rotate the logo, you will see that there is absolutely no Extrude on it.

This is because the pixel depth value is connected by the Curve Depth which is Zero in this case.

Increase it by one pixel.

You should see the Extrude now because each layer is separated by 1 pixel in Z axis.

Step 13

Bring on the Mask options of the Logo100 layer and use the following settings and solo it to see the preview.

Step 14

The reason I did this is to get a thin line of the logo.

I kept on decreasing the value of Mask Expansion with each layer which helped me to achieve the desired effect.

You can see that the value of Expansion is decreased by 3 in each layer from 100 to 86.

From 85 to 63 the value is separated by 2.5 per layer.

From 62 to 54 the Expansion value difference is 2 in each layer.

From 53 to 32 the difference is 1.5 in each layer.

In all the remaining layers the Expansion value difference is only 1.

Step 15

You can see the curve effect on the logo because the mask kept decreasing over the layers in Z axis.

Here is a side view of the logo.

While taking a closer look, you can see the top edges of the logo are not Extruded while the central part is Extruded.

This is also one reason to use Logo comp with small Height value. The Mask Expansion value of bottom layers are almost 0 and the above ones have bigger value than the bottom ones which cuts off a small part of the logo from the edges thus faking a curve effect.

Step 16

Change the logo to see if it works with everything.

You should see something like this

3. Controlling Shadow, Extrude Color, and Overshooting Effect

Step 1

Now to control the Extrude color, Lock the Controller Layer Panel.

Step 2

Open the Logo+Stroke layer and connect the color of the Fill effect with Extrude Color.

You should see something like this.

Step 3

Change the color to see if everything works fine.

You should see green shaded sides.

Step 4

Duplicate the Logo1 layer and rename it to Shadow.

Step 5

Apply Fill and Fast Blur effects with the following settings.

Step 6

Make a new Solid and name it BG. This will be used as the background to see the shades and shadows properly.

Step 7

Put BG layer under all the remaining layers. Also duplicate the Shadow layer.

Step 8

Apply CC Radial Blur effect on Shadow 2 layer with the following settings.

You should see something like this:

Step 9

To make an Overshooting Extrude effect, it is important that the Extrude and Shadow react the same way. To do this, connect the Amount Value of CC Radial Blur to the Curve Depth effect on the Controller layer. Alt+Click on the Amount of CC Radial Blur and insert the following Expression.

thisComp.layer("Controller").effect("Curve Value")("Slider")*7.5

I Multiplied the Expression with 7.5. Which means if the value of Extrude is 1, the value of shadow will be 7.5 to match up with the density of Extrude.

Step 10

To make an Overshooting effect, Make few Key frames on the Curve Depth Value.

Here are the values I used for the demo.

Step 11

Then Alt+Click on the stop watch and insert the following Expression.

n = 0;
if (numKeys > 0) {
n = nearestKey(time).index;
if (key(n).time > time){
if (n == 0) {
t = 0;
} else {
t = time - key(n).time;
if (n > 0){
v = velocityAtTime(key(n).time- thisComp.frameDuration/10);
amp = 7.5;
freq = 1.5;
decay = 2.0;
value + (v/100)*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);

This expression is used and shared by a user on Vimeo. Here is the link to the expression. Credit goes to its due authors for creating this amazing Overshooting Expression.

You may want to play with the values of amp, freq and decay. The distance between the Key frames and the value of Curve effect will also affect the Overshooting effect which you can see from the preview video.

Step 12

There is one more interesting thing that you can do. You can put a negative value for the Curve Depth and you will see a Reverse Curve Extrude.

You should see something like this.


In this tutorial, we learned how to create a curved extrude effect with the help of the mask and its expansion value. We decreased the value of the expansion with each layer to achieve a nice looking curve. Additionally, we learned how to achieve an overshooting effect with the help of a little script and got some different looks with the help of our controller layer.

Note: You can play with your own mask settings to get a unique curve effect. Just change the values of Mask Expansion accordingly in all the layers to see what works best for you.
